August 5, 2008 Toyota has been heavily engaged in the development of personal mobility devices and partner robots in recent years with a series of concepts such as the PM (Personal Mobility) Concept, the i-unit and i-swing , and more recently the armchair-shaped iREAL, which appears close to commercialization. Now the company has announced he development of the Segway-like "Winglet", a small footprint stand-up mode of single person transport that will cruise at 3.7 mph (6kph) at a range of up to 6.2miles (10km). Three models (which at this stage are simply designated "L", "M" and "S") are proposed: the larger version features a handle and weighs in at 12.3kg whilst the lightest of the two hands-free models weighs under 10kg but can only manage 3.1 miles at a time. All models share an impressive charging time of one hour.
